Flamewall for a holo Acheron
You give your only Flamewall (Mythic #6, 3,400 pts) and get a holo Acheron (Legendary #27, 1,100 × 3 = 3,300 pts). Points: −100, a small loss. Rarity: a holo Acheron takes about 14,915 packs to pull, Flamewall about 2,582. Take it if you collect rare cards; skip it if every point counts.
